Application inea Ap'rn 1, 191e, serial No. 878,407.

To all whom t may aannam.'

Be it known that we, EDWARD KELLY and EARL REYNOLDS, citizens of the United States, residing at YBradley Beach, in the county of Monmouth and State of New J ersey, have invented certain new and useful Improvements in Va orizers for Gas-Entwo independent gasolene holding compart-- ments which may be filled to a certain predetermined level and which, at a point above this level, communicate with each other and with a fuel mixture or-carbureted air chamber or compartment from which a supply pipe leads to a carbureter.

A still further object of our invention consists in the provision of means whereby air may be supplied to each or both of the gasolene holding tanks at a level below the gasolene contained therein in order that the suction in the tank created by the movement of the pistons in the engine cylinders may draw the air so supplied lthrough the gasolene to vaporize the gasolene.

In this connection, a still further object of our invention consists in the provision of a suitable lcheck valve in the pipe supplying the explosive mixture to the engine toprevent danger of explosions in the tank, due to back firing and to provide a safety valve to prevent bursting of the pipe between the engine and check valve in case of back firin p .A still further object of our invention consists in providing asupplemental fuel tank of relatively small capacity which may be mounted withinthe hood of the vehicle and' from which gasolene may be supplied directly to the pipe leading to the engine manifold for the purpose of priming the engine, a suitable form of valve vbeing furnished .to control the supply of .priming4 fuel.

With these and other objects in view, our

invention will be more fully described, illustrated in the accompanying drawings, and then specifically ointed out in the claim which is attache to andy forms a part .of this application.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

fOur invention includes a main fuel tank or reservoir 10, preferably constructed of sheet metal in the usual manner and either rectangular or cylindrical in shape, as preferred. This tank is divided into spaced fuel chambers 11 and 12 separated by a fuel mixture chamber 13 by means ofthe spaced vertical transverse walls 14 and 15.` As shown in Fig. 3 of the drawings, -these walls, adjacent the top of the tank, are formed with openings 16 by means of which Acommunication is established between the. chambers 11, 12 and 13. rIhe end walls of the tank are formed with filling spouts 17 through which the-fuel chambers 11 and 12 may be filled and in vwhich fuel will appear before c los ' openings 23 by through the pipes 20 may esca e from the or other Aimpurities 'abcumulating in 'these' be withdrawn from time to through' the top wall 'of the tank 10 into the chambers 11 and 12 and, at their lower ends,

carry hollow disk-shaped nozzles 22 which f' are supported by the pipes in sli htly spaced relation above the bottom og the tank.. These nozzles, in their upper and lower faces, are formed with'a .plurality of A means of which -air drawn ,nozzles and pass upwardly t rough the gasolene contained in the cham'berslland 12. Eachof the pipes 20 and 21 is provlded with any suitable form of manually operable cut-off valve 24 and an air supply pipe25 is connected at one end to the pipe 20, orming a continuation of this pipe and is also connected at a point within its len `h with the pipe 21. This pipe 25, at its ee end, opens mto a funnelshaped member 26 forining the air intake of the vaporizer. This member 26 may be disposed with its liared open end adjacent the exhaust manifold Aof i ing jacket, as preferred, in order that the the engine or in communication with a heatair supplied through the pipe 25 may be Atank 10 is formed wlth an opening 27 to receive a suction. head 28 which extends into the fuel mixture 'chamber 13 of the tank. This suction head is preferably in the form of a sphere having a circular series of openings 29 formed in it immediately within the tank andcarrying, below this series of o enings, a concave-convex baiile plate or de ector 30 disposed with its concave face outermost and acting to prevent splashing of fuel into Athe-suction ead and to cause a' uniform drawing of vapor from all of the chambers into the head; A pipe 31 leads from, this suction head to a. valve cas' 32 having a flan 33 adapted for connection to the corres on ing flange pf the intake manifold, not s f free .terminal of one own, of an engine. Q

This valve casing 32 is substantially L- shaped, the flange 33 being formed at the arm andthe pipe 31 beconnectedA to the free .terminal of the itt -o er arm. This second arm is enlar ed iutermediateits len h to form a cham erfrom'the p1pe 31 to the 34. inclosing a chec valve 35 which may open through suction of the enginecylinders to permit passage of a combustible mixture cylinders,'but which automatically lclose to prevent any return assage of the mixture and, conse-- quen y, to rotect the tank` and its contents arm of the valve casing against bac firing of the engine. The other is rovided with the usual throttle valve 36 o the butterfly type and such arm, at its point of juncture with the cheek Ivalvecarrying armpis pref erably formed ywith a cylindrical extension providing a valve chamber 37. This valve chamber communicates directly with the atmosphere and incloses a valve seat 38 and coseat-'by va sprin check valve an a flange 41 formed interiorly' of the open endof the chamber' 37. Obviously, in case of back iirin the burn; ing gases from the engine cylin ers, if they pass the. intake valves of the cylinders, may escape from the valve casin 32 by assing through the valve 39 and all anger o bursting either, the intake manifold of the en 'ne or the valve casing 32 is, therefore, avoi ed.

Although the above described structure comprehe'ndsl all the vital features of our invention, we preferably make a special provision for'prnning the engine cylinders. To accomplish. this, we providea supplemental fuel tank 42 of relatively small size which may be secured to the dash 43 of the vehicle within the hood'or at any suitable point at l a level above the valve casing 32 and which is formed with a filling opening normally eads from a cylindrical valve casing 46 and a pipe 47 leads from the outer end of this valve casl to the pipe'31 at a point adjacent the'valve casing 32. The valve casin with a valve seat 48 located in that end of the casing communicating with the ipe 47 and adapted to coperate with a'needie valve 49, the stem 50 of which isthreaded through the opposite end ofthe valve casing 46 and provided with a handle 51 by means of which the valve may be opened or closed.

With the above described vaporizer, when the vehicleis to be started, one -or both of the valves 24 is opened, the valve 49 is opened to such an extent as to permit a predetermined iiow of pure gasolene tothe pipe 31, vthe throttle valve 36 is opened in 46 is provided actingvcheck valve 39 normally held to its., 40'engaging between the pipe 25 'and pipes 20 and 21 and from such tank through the pipe 31 and valve casmg 32 to the englne manifold, this air meeting the pure gasolene entering the pipe 31 from 'the pipe 47 and mixing withit.

After the engine has been running for a short time, the air admitted to the tank 10 will be heated and will take up gasolene during, itspassage through the chambers 11 and 12 and thus form an explosive mixture within the tank 10, which is drawn through the pipe- 31 to the engine. As the air beiA comes suiliciently heated, this mixture will maare@ become rich enough to form a suitable fuel for the engine, after which the valve 4:9 may be closed and all fuel drawn directly from the tank 10. As previously pointed ou't, the check valve 36V and safety valve 39 serve to protect the vaporizer in case of back firing of the engine. Preferably, the suction head 28 is provided with a transverse strainer 52 which extends transversely of the head between 'the intake openings 29 and the pipe 31 to prevent the passage of'impurities to the engine.

It should be noted that the heated air continually passing through the liquid fuel contained in the fuel chambers heats the fuel to a considerable extent and inasmuch as one of these chambers is disposed at either side of the vapor chamber, it will be clear that all fuel mixture generated in this chamber is kept heated until it is drawn into the engme.

Although we have illustrated and described our invention in all its details of construction, it will of course be understood that We do not wish to limit ourselves to such details, as various minor changes, withm the scope of the appended claim may be madd. at any timewithout in the slightest degree departing from the spirit of our invention.

Having thus described the invention, what is claimed as new is:

A vaporizer for internal combustion engines including a tank divided into fuel and fuel mixture chambers in communication with each other, an air supply pipe extending into the fuel chamber and below the liquid level therein, a suction head extending into the fuel mixture chamber of the tank, and a pipe leading from the suction head to supply the fuel mixture to the engine, the suction head being substantially spherical in shape and formed with a series of encircling openings, a concavo-convex baiile member secured to the head below the openings with its concave face directed downwardly, and a strainer across the head between its openings and 'the pipe connected thereto.

In testimony whereof we ax our signatures. F
